To (nl Y107mmtmag/ concern.:

f- Be it known'that I, FRANCISv R. FLYNN, a citii/.enl of tlicllnited States, residing in the city of New York, borough of Bronx,l

county of Bronx, and State of New York, have invented a certain new and useful Conilnned Tniied-Lock and Recorder,- ot which the following is a specification.

and recorder, and thel object of the invention is to permanently record, `in a siinple,eii cient, and enact. manner; the precise times .-vhen a lock' is operated. I

Speaking more specifically,v the invention embodies improvements whereby a lock, 'in- .stalled on a doorisso'arranged in conjunction with a time train and time recordvA ing mechanism, that, when; the lock isoperated to either open'or'closethe door, the pre'- `eise time efsaid operation is recorded on a chart..

A Among the novel features einbodiedjin the invention may he -mentioned the ffollowing: rst, theemployment. ofa chart supporting drum on ivhichis Wound' a removable' time chart; second; n nf improved time chart `drinn wher'ebytheemployment 'of *padding beneath theti'me chart isobviated,jand pronouncedladvantages secured; third, means cooperating with the drum and operable by the moveni'cnt of the holt of the lock for the pui-posent causing said means to record on the eliai't tlie. .times ot' operation of the lock; fourth, bolt operating means cooperating with. 'niechanisnifor locking the bolt either `its locked or drawn positions, whereby surrcptitious operation` ofltlie bolt is'pre- .cliided;" ffth, means ceperating'with the loekingfmechanisni 'whereby complete locking'oxunloekiiig operations and consequent reeordingof time is imperative upon the Aslightest movement of said mechanism; and

sirlh.;.nove1 means for securing` a chart to its 4 l supporting drum. Y

Inioneef its practical 'forms the inven- .tionembodiesa time train. a. drum adapted to support 'a chart, said drum being driven at 'a constant speed by the time train, a iuarkeradaptedto cooperate with the chart on the drum, sa'id marker being mounted for movement longitudinally1 of the axis of the rotation'of said drum, said imivement being imparted also from the tifne train, whereby the coperatmg marker and chart are moved in synchronisni. in combination with a bolt` of the type which isuadapted to. beslid to his invention is a combined timed lock'y and fro for the purpose of locking or iin- Vlocking thevelosure to which it isapplied,

ineansop'erableby the-sliding movement of the .bolt for* actuating the marker and`thus cause designations to be` made upon the -chartg I also provide means which maybe utilized, vif desired, tov clearly distinguish the .recordset the locking operations from {he-se of the unlocking operations of the Jolt. f ,i f

Features of the .invention` other than those specified will be vappa-rent 'from-'the following description, read in conjunction with the accompanying drawings. l

ln the accompanying drawin s I ,have illustrated different racti'eal' eimhdiments of the invention, but t e constructions shown therein are to be understood as illustrative,

Fig. 23 is aface elevation of the mechanism illustrated in Fig. 21, and

Fig. 24 is a transverse sectionthrough the chart perforating mechanism therein shown.

Referring to Figs. 1to 15, inclusive, of the drawings, wherein the preferred'cmbodinient of the invention is illustrated, A denotes, what I prefer to designate, the back plate of the device. On this plate the mechanism is mounted, whereby it may be fastened to a door or other closure.V Intermediate the ends of the plate A, and on the same side thereof, is a pair o f forwardly projecting brackets, a, a. These brackets are tightly secured to the back plate, and carry a rotatable spindle B, which rests in a journal on the bottom bracket a', and

passes upwardly through'the upper bracket a, and is thercabove provided with a bevf .led pinion, d. Between the brackets, loosely mounted on the spindle, B', is a chart carrying drum heretoforenientioned. Ex-

' terior of either end of said' drum, collars, b,

b', are fixed o n the spindle B, and intermediate these collars. and the corresponding ends of the drum are positioned resilient spring members Thus, although the drum is loosely mounted, as far as rotation is concerned, on the spindle B, it is manifest that the tension exerted by the resilient members, c, will cause said members to coperate with the cfids of the drum after the manner of a. friction clutch. Accordingly, if power were ',supplied to the spindle, B, through the pinion, d, the friction clutches would trans-- mit the rotary motion to the drumnnder normal conditions'. difficulty arise in the operation of the drum, or if it is desiredto reverse the mechanisml for any means whatever, the power exertedby the friction membersl would be insutiicient to hold the drumv and its spindle against relative rotation, andi said drum would be allowed 'to slip sulticiently to preclude breakage or allow adjustment.

Accordingr to my invention. the` drum Should he revolved at a constant speed', and accordingly, l provide a suitable time train or clock mechanism, D, which is mounted on However, should any4 the upper bracket anand so positioned relative to the beveled pinion, cl, that the operation of the time train'- transmits rotary.

motion to the drum, C, through the pinion, (l.

minted on the lower end of the drum,

coaxial therewith, and set oil therefrom on the p'osts.l f, is a gear, F, which gear meshes with a pinion, E, fixed on a Worm, e, which is positioned parallel to the spindle, B` and is journaled at either ends in the. brackets,

a, a. On the worm, e, is mounted a rocking arm or lever, Gr, and. this arm' is operated by meansof a cam spindle mounted between the brackets, a and a', which cam spindle engages with the power arm of the lever, Gr. The working arm of the lever'is .provided with a threaded tap into which is screwed, for adjustment, a needle.l pencil point, or other suitable recording mechanism which, when .the rocking arm is oscillated, will serve to indent or otherwise. lsuitably inark a chart wound upon the drum, C.

lVhile many forms ofl charts may. be employed, the one next to be described'has been found to vgive very good results, and a clear,

unmistakable, exact record-of data desired.

This chart, Iis generally formedfrom a strip of papenlight cardboard, or other material and hasformed-upon its face, section lining extending both longitudinally and transversely thereof. The transverse are preferably,,substantially` perpendicular to longitudinal edges ofthe chart and, in the preferred form, designate a predeter-v mined length of time. The total length of the chart, i.- e., the, 'circumference of the drum, C, preferably represen-tsl? hours, so that wheir the chart is wound upon the drum, 2 revolutions of the chart 'constitute a day of 24 hours. For convenience in reading the chart, it isdivided up longitudinally into hour, half-hour, and ten minute spaces, and, since it s-desirable to have' thel chart extend over a period of' several days, these days are laid oti' by the longitudinal lines,"

each two' spaces representing a day. It will be seen from the chart illustrated in Fig. 11 that there are 16 vertical spaces, which de note the a. m. and p. m.Y of 8 days. While,

iio

if desired, tite names of .these days cduld be' printed opp .site the respective .a m. iand p; m. spaces thereof,it is impractical, from a commercial standpoint, since all the charts would not be installed inthe differentv machines on the same day. It is desirable that,-

wlien a' chart is put into a machine, the plotting or marking operation start at the top of the chart so that it would not be necessary to return to the .machine and put in a new chart for a. week 'or 'eight days. Coin sequently, a small ci rclc, designated. i, isprovided en the face of the-chart so that when the chart is put into a machine, the workman may mark a numeral 1, 2, etc., desighating respectively, the first, second and third days etc., of theweek. Thus, if the numeral 1, is'found in the circle, z', anyone looking at the chart, and conversant with the same, wouldA understand Vthat the chart reads from a Sunday. Ifthe numeral 2 lvere found, itwill be understood that the chartwas inserted on Monday, etc.

The longitudinally extending lines on the chart are not parallel to the edge thereof,

but ari: parallel to each other, and slope downwardly so that whenvthe chart is wound `upon the drum, each line on the chart will match with the succeeding line thereon, so

as tofextend from near the top of the chart in the form of an entireand unbroken helix will, after twelve hours, or one rotation of thedrum, become a p. m. space, and subse- 'chart is wound thereon.

quently an a. m. space, etc., alternating every twelve hours.

There are .many ways in which the chart, I, may be installed upon the drum, but, as it s 'quite necessary that thc .longitudinal edges of the chart be parallel with the top and bottom Afaces of the drum, I have found that the following method of securing the chart in place is .decidedly practical. Drum, C, is provided with a slit, j, extending from the upper to the lower edge thereof, and the upper.` face of said drum, adjacent to the slit, y', is provided with an enlarged aperture, j', to allow. the passing of a pm or-hodkin through'the upper wall of the drum into the interior thereof. In securing thevchart to the drum, the drum is turned so that the slit; j, is at the frontof the machine', and within easy access of the operator. The end of the chart is then wound or looped about the--pin orvbodkin, .Hand the bodkin inserted into the aperture. j, in the top of the drum, after the manner illustrated in` Fig. 10 of the drawings. The chart is provided at its other end with a small transparent tab, i, referably gummed on its rear side. After this tab has been moistened, the operator. rotatesl the drum, whereupon the. For facilitating the securing of the gumme'd tab, 11, I preferahly, provide a wiper, K, mounted on` the back p1ate,`A. Thus. as the drum is rotated` the tab passes` under the wiper, and is pressed down and secured in place. I pref.- erably make the wiper of width coextensive with' the width of the chart, so that during the operation of wiping the tab in place, the

chart is smoothed out, and all wrinkling thereby precluded.

The wiper is preferably inthe form of a broad leaf Spring, K, whichV is secured to the back plate by means of screws or the like. This wiper 1s normally out of engagement there against by a cam, k,pivoted between the brackets, lc', and operable by a handle, k2. Thus when it is desired to install a chart on a drum, the cam is operated to impel the wiper against the drum, as shown in dotted lines in Fig. 3. At all other-tin|es, however, the cam is in its idle position, a. shown in Yfull in said ligure, and the wiper is thus allowed, by virtue of its tension, to remain free from engagement with the drum.

Although I do not restrict myself to thev form of drum illustrated -in the drawings, I have found said drum to be extremely'eilicient. In the form of mechanism illustrated the designating or marking member is in the form of a perforating pin, g, and it pricks holes in the chart at the desired times. To facilitate the pricking of these holes, the drum may be padded, but ,this padding has its drawbacks, in that it is dilicult to correctly maintain the chart around a padded drum in its proper position, hence the improved drum. The improved drum, 'as shown more particularly in Fig. 10, is provided with a continuous helical channel leading from near the top of the drum to close tol the bott-om thereof, and formingbctween its successive convolutions a comparatively sharp rib, c. The pitch of this helical rib, c', is equal to the. pitch of the helix formed by the lines on the chart when the same is in place on the drum, with the with the drum, but is adapted to be impelled tinct prick may be made withoutendangering the point ofthe perforating piu, g, by its comlng into contact with the. hard face of' the drum. Moreover, by the use of the improved drum, all padding is ohviated,

and the chart may be wound upon the drum with accurate precision.

From the foregoing description, it will be manifest that the time train drives the drum, C, and the worm, e, insjrnchronism, i. c., as the drum is revolving, the worm is turning-to lower the rocking arm in timed relation to the rotation of the drum. Conse-A quently, when the chart Ais positioned on said drum, the relative Velocity of the drum and the rocking arm is such that the perforating needle will travel downwardly over the successive, helical convolutions of the chart. In the structure shown, the chart is adapted to make one revolution every twelve hours, and, since the Chart is adapted to record eight days, the movement of the rocker arm and perforating needle from the top of the chart tothe bottom thereof, tracking all'the whilgthe 'convolutions of the chart will. occupy the space of S days. llfanifestly the Perfoi'a ting needle and the chart are so-relaf tively positioned, at all times, that, vif the Lrockingr arm is operated it will invariably. perforate said chart betweenpthe Yadjacentthe bolt of the lock, which eoperates therewith, is -moved Vto or fro to lock or unlock the closure with which it is associated. T-he operation of registering these movements of the bolt will next be described.

The bolt, L, is mounted on the back plate, A, below the bracket, 0.', and is retained `against removal by a keeping plate, l, se-

cured'lo thebaek plate by screws, Z'.

'I Formed in the bolt, L, is a rack', lll, with carrying drlun.

which coperates' a pinion, m, fixed at the lower vend and beneath the bracket, a', on the caml spindle, H. Thus, when theA bolt is slid back andforth to its locked or lunlocked positions, such movement imparts ro. tary motion to the cam spindle`- H, with the result that the working end of the rocking arm, which carries the .perforating needle. is moved toward and away from the chart A leaf spring,'g, is secured on the rocking arm, and, at. all times, presses against vtheearn spindle, Il, for the purpose of retaining the power arm of the rocking lever, g, in engagement with the cam spindle (see Fig. The size of the pinion. m. and length of the rack are such. howerer, that the movement of said bolt to either ot' its operative positions will give the cam slzal't Lut one complete turn.

cordiugly, when the bolt is moved to the-opadapted to engage a notch, Z2, in the upper. A tubular sleeve, O, ex-e edge Of the bolt. tends through the thutknlss'of the door and into itsouter end is inserted ordinary key\ reception means, 1,'. gl, barrel, 0. of a yale lock. with the usual'wards and plungers.

The rotary portion of said'barrel, o, is provided, at its end, with a polygonal blank, which is securedlagainst rotation thereto, and isadapted .to engage with a slot, o2, in the adjacent endV of the plug, N. Thus, when the key is inserted into the barrel, o, and turned, the rotary motion will be imparted through the blank, o', to the plug, N, which movement'will swing the wing, n, thereof, thereby resulting in sliding movement of the bolt, L. y

During the foregoing operation of shifting the bolt to its locked or unlockei positions, the rack, M, pinion, m, cam spindle, H, and rocker arm, are cooperating to pro. duce the record. ofsuch movement on the chart. 'In order to preclude any attempt to beat the lock, it is deemed advisable to provide means, whereby the perforations designating the locking of the bolt may be clearly distinguishable on the chart, from those corresponding`to the unlocking of said bolt. I, therefore, provide means whereby the perforations, formed on a locking op'- eration, are indifferent planes from the perforations occasioned by the unlocking of said bolt. This'means' is embodied in a car rier plate,- P, which is pivoted to 'the back plate, A, by meansY of the screw, p. One end ofA this plate is provided v,with arms, p', p2,.which engage with the worm, e, in such manner that, when the plate, P, is oscillated inA one direction, it willserve, to depress the worm,`\vl1ile in aA counter direction lwill cause the elevation of said worm. The mechanism isfso adjusted that, in the elevated position, the marker will tra-verse the chart ucar the upper edge-of the space over which it is traveling, while on the depressed movement. if the marker is operated, .it will mark the chart near the lower edge of said space. Thus, the locking operations of the bolt will be. made'along the upper edge of the space, and the unlocking operations along the lower edge thereof, with the result formed on the wing, u, 'of said plug. This trip engages with an eccentric, pforrned in the plate, P. Manifestly, when the plug. N, is operated, as aforesaid, to unlock e lock the bolt, the tri n', will 'copera'w with the eccentric to epres's and lower th"- worm alternately, according to the move. ments occasioned by the locking or unlocking of the bolt.

Mariydoors are so hung that,. the free edges thereof do not fit tightly into theV doorway, and in some locks it is possible to shut partly withdraw the bolt in order to open thcvdoor. is essential that,.e\'ery movement of the bolt, no matter how slight, need be recorded, and

In a device of this class, it .Y

with this end in view, I have provided means i than the distance from its point of pivoting to the base of the teeth of the ratchet, and cannot, therefore, be positioned in a direct line with the ratchet wheel, except at one portion thereof where the teeth are cut away, as at o3, and this cut awayportion is so positioned relative to the wing, n, lon the plug, N, that, lthe pawl can only occupy this cut away portion when the bolt is entirely locked or unlocked. Thus, when the-opera.- tion of moving the bolt 'is started, the pawl swings to one side of the center line, passing through the axis of the plug and thev point of pivoting of the pawl, and, upon the turning vof the plug, engages with the successive teeth on the ratchet. The springs, o, retain the pawl in engagement with said teeth. Thus, after the operation of moving the. plug andthe consequent movement of the bolt has been started, the pawl will engage with the teeth of the ratchet, and preclude the return operation of the bolt, until the same has been moved its entire travel, andthe consequent recording accomplished.

YIn the operation of the lock to throw or withdraw the bolt', the operator inserts the key and gives it a fraction of a revolution more than a -co1nplete turn. This brings about the desired result of locking or unlocking the closure, and brings the paw] to the cut-away portion of the ratchet, so that pon the withdrawal of the key, the parts are left in such position that the key may be inserted again when it is desired to reverse said operatiom'and said operationimmediately proceeded with. It will thus be noted that it is `necessary to give the plug, N, a

9 'little more than one complete revolution, in

' order to slide the bolt its entire travel, be-

notch, Z1'. Thus, when the lug is turned and the wing, u, disengaged rom the notch,

l, the projection, nf, immediately engages one of the notches, l, and the bolt is, practically at all times, engaged by some part of the plug, N. Thus, if the plug is retained against return movement, the bolt is likewise retained. Con'sequently,in the normal operation of the lock, z'. e., the imparting of a single revolution to the key, the bolt, when the key is withdrawn, will be left in retained form, z'. e., it cannot be surreptitiously operated with a screw driver or the like to shift the bolt to another position. -The proper key must necessarily be employed to com-4 plete the operation before the same can be reversed.

In the practical operation of the present invention a chart is inserted into the drum, as heretofore described, the prime mover of the time train, e. g., a spring is wound up, and the mechanism is left to operate for a week or eight days. At the end of a week the inspector returns, removes the weekly record chart from the drum, and installs a new one in its place. At the same time turning back the worm, e, to bring the rocker arm at the top of the chart in the position to start Ynext weeks record. To facilitate this turning back of the worm I preferably form a beveled gear, Q, on the drum spindle, B, with which beveled gear is associated a pinion, tv', mounted -on the bracket, a', in a bearing, g, and having a spindle with a polygonal end with which a key is adapted to cooperate. Manifestly, the turning of the key on the spindle -of said pinion will impart movement through the beveled gear, Q, the gear, F, and pinion, E, to the worm, e, whereby the rocker arm may be elevated, as desired. In order that said key may be inserted into tl1e'casi11g, an aperture, QL', is formed therein (see Fig. 12) and this aperture is normally closed by a plate, Q2, one

arm of which is engaged by the door, A', of

the casing, when the same is swung shut. Thus, when the door, A', is closed and locked, the plate, Q2, cannot be shifted from the outside of the casing for the purpose of surreptitiosly inserting the key to tamper with the lock operating mechanism, How-A ever, when the door is open, the plate, Q2, may be swung away from the aperture, ([2,

. as shown in dotted lines in said figure. and

the key may be readily inserted. I wish it understood that, although I have described special means for returning the -lock arm to its initial operative position, the same is not absolutely necessary, since the drum may readily be revolved by hand to bring about dhe desired result. In either instance the drum is allowed to revolve conversely to the impelling action of the time train, because of the fact that said drum is not positively vconnected to the drum spindle, l, but simply -frictionally connected thereto.

Having fully stated the preferred embodiment of the invention and the operation of the several distinct `features thereof, the complete operation may be briefly set forth as follows The chart having been properly positioned on the drum, and secured in sentinel of the closure with which it is Vassociated., When it' isI desired to lock the door,- the key is inserted into the barrel, o, of the lock, and the plug, N, operated to swing the wing, n, thereon and slide the bolt into locked position. Simultaneously with the movement of the bolt the rack, M, imparts rotary motion to the cam spindle, H, with the result that the chart is perforated, thereb`y recording the time of the sliding of the bolt. Before said bolt has, however, completed its travel, the trip, n', on the plug, N, is engaged with the eccentric portion, p3, of-the plate, P, and elevatcs the worm so that the perforating needle is in the position to make the next perforation.

AThe operation of .sliding the bolt its entire travel, either into locked or unlocked position, requires a little more than a eomplete revolution of the key, and the plug, N, 25 is so adjusted, relative to theA bolt, that when the bolt isrin its locked or unlocked position, the projection n2, on said plug will coperate with one of'the notches, n, on the bolt. '.l`hus, in the locking or unlocking-operation of the bolt, the operator gives the key a trifle more than one revolution, so

that, when the key is withdrawn from the wards of the lock barrel, the pawl o, will be in the cut-away portion of the ratchet and the lprojection n3, will be in engagement with o ne of the notches, Z3, of the bolt. Consequently, when the operation of locking or unlocking the bolt is completed, the parts ofthe lock are left, upon the withdrawal of `the key, in such position that the key may be inserted again when it is desired to rcycrsc the operation, and the said reversed operation immediately proceeded with. However, when in locked or unlocked position, the bolt is adequately retained against surreptitious\.movement, by means other than the lock barrel, by the engagement of the projcctionf'n, with one of the slots, l, in the bolt, -said plug being maintained against shifting by virtue of the friction bctwcen itsc f and its bearing.

I have/bj1.. t forth in thc foregoing description, one particular form of chart embodyingr both transverse and longitudinally dis- 55 posed' markings. I have found, however, that-'the longitudinal markings are not ab- `lstrliit ely\compulsory in the manufacture of the'clvirt, if a chart, devoid of such markins,\.\is placed upon my improved .-5.0 drum, -and the drum-rotated with the wiper,

- K, in contact\\v\ith\ thechart, the pressure said wiper (xiperating with the comparaiaely sharp edgcrof the rib on the drum willadequately mark the drum with longitudinally extending creases, which correspond to the inked sectioning illustrated' in the drawings. This arrangement and method of marking the chartwill give an absolutely invariable record. I have also illustratedthe worm as adapted to longitudinal movement subject to movement of the bolt. I may, however, make the worm stationary, and correspondingly move the drum instead. The form shown is the best, however, and I have .illustrated it for this reason. Another advantage which will be apparent is the fact that the lock is adapted for use in conjunction with both right and left hand closures, it being manifest that, by the provision of the extra rack, lM', the bolt may be turned end for end., so that the rack, M will coperate with the pinion, m,

Having now described, at length, the mechanism, function and operation-of the preferred form of the invention illustrated in Figs. 1 to l5, inclusive, attention isA directed t'o Figs. 1G to 24, wherein is shown` a modified form of the invention. This modified -form is, in most of its features, very similar to thepreferred form; yet, some details are changed, as will be hereinafter more fully explained.

In said figures, the casing is designated by the numeral 1, which, like the casing of the preferred form, -may Abe of any desired shape or configuration. In the upper part of the casing is positioned a clock mechanism or time 'train 2, the operating spindles of which preferably pass through the-front of the casing and are provided with' means inclosed beneath a.- glass dial whereby said time train may serve as a clock to advise persons as to the time of'day.. 'lhe'time thedriim 7, and the worms 11, 11, are rotatcd in'synchronism bythe time train 2.

T he drum 7 is adapted to carry about its periphery a removable recording Vsheet 12,

similar to the char!J I, hereinbefore mentioned, which cha-rt is adapted to receive records of the movements of the bolt 13, of the locking mechanism through the coperation therewith of-suitable marking mechanism. This mechanism, according to this form of the invention, is mounted on a horizontal bar 14, carried on the worms 11, 11, andby "irtue of said worms, movable longitudinally of the -axis of rotation of the drum 7.

The marker device consists of three needles penetrating separate orifices therefor,

as guides, in bar 14, said'oriices being in the Y head 19, is held out of Contact with the time sheet or chart by a spring 20, of less ten'- sion thanfspring 17, lying between head 19, and bridge 16. v

The needle points are held normally adjacent-to the surface of the time sheet or chart, whichthey are adapted to strike and impress in the range of their retractile movement. Pressure against the head 19,

of the needle 18, will project that needle in wardly without correspondingly moving the needles 15, 15,` because' the tension of the. spring 20, is insufiicient to influence sprmg 17j, and pressure against the bridge 16, will project the needles 15, 15, forwardly, independently of the needle 18. Thus, the needle 1S can be used to record the movement of the bolt in one direction, and the needles 15, 15, can be used to record themovement of the bolt in the other direction.

The means for actuating the marking needles include a pair of flaps 21, 22, hinged,- respectively, to bar 14 at opposite sides of said needles, said flaps being normally outstanding at right angles from bar 14, and being capable, through the agency of coiled springs-23, of returning to said position, in the manner of swinging doors, after 'being moved in either direction. The flap 21 has a finger-like form and is adapted, when depressed inwardly, to bear against head 19 of needle 18, causing the latter' to attack -and mark the time sheet or chart, but without moving the needles 15, 15. On the other hand, if the Hap 22, which-is of forked, or bifurcated character, is pressed inwardly, it will straddle the head 19 and willV meet and exert 4pressure upon lthe bridge 16, therebyforcing the needles 15, 15, against the time Isheet or chart, causing the creation of two marks thereonw Y l i The flaps 21, 22, are operated by a swingintr arm 21, mounted on a vertical, pivotal rod 25, disposed midway between said flaps, the ,height of said arm covering the range of movement of bar 14, and said arm, 1n its swinging movements, serving to operatively Adepress both flaps 21, 22, Said flaps have teeth, 21, 22, respectively, on their outer surfaces, to permit the -inward and forward movement thereover of arm 24, in depressing a flap, but to prevent return of Ygaat ,the .but

said arm until the flap has swung out again on its pivot.

The pivotal rod 25, on which theswinging arm 24, is mounted, extends downwardly through the casing and is provided with a segment 2G, adapted to coperate with a rack 27T, formed in the bolt 13, whereby sliding movement of the bolt into its locked or unlocked positions will impart movement to the rod 25; for the purpose of operating the chart-marking mechanism,

The means for shutting or retracting the bolt comprises the barrel of an ordinary Yale lock28,4 to which is lattached a rod 29, fxedto the end of which is a gear 30, cop- Ierating with a rack 31 onthe upper edge of the bolt 13. The lock barrel 28, is operable `by means ofthe usual key, whereupon the rod 29 is rotated and thev gear 30 utilized to Hence, when the' key is turned. in one direction, the. bolt will be shot out wh-ile, if turned in the other direction,v thel bolt will be retracted, these movements being communicated through the rack 27 j and segment 26, to the rod 25. -The rod 25 will .operate the swinging arm 24,- whieh will, in turn, cooperate with the flaps 21, 22,

to actuate the marking means and produce indications, ou the chart.

It will be noted that the chart illustrated vini this form is slightly different from the chart hereinbefore described, in that, by the arrangementiof parts shown, the drum ro- 1 tates in an opposite direction to the drum of the preferred form. Accordingly, the chart is made conversely.- Moreover, the chart 12 is illustrated as a seven-day, instead of an eightday, chart.

In order that the marking mechanism may be raised to its elevated position for a period of seven days from its initial operation, av worm 32 is positioned to-coperate .with the gear 9, to bring about this result, and the spindle of said worm passes outside of the casing and is provided with a 'finger piece 33, to 1allow of convenient. manipu a-' tion of the worm. Fromv the foregoing description {itibecomes` apparent that both4 forms -of 'the'in. mention described embody meanswhereby it is rendered impossible to register less records than operations,4 and, since the designa tion on the chart, corresponding-` to the unlocking oi the; bolt, isclearly differentiated from that made upon the locking operation thereof, it is impossible to "beat the lock by a simultaneous locking and unlocking operation. Consequently, the chart will show, at the end of any stated period, al

-clear,unmistakable andinfallible record of every operation of the lockinglmeans.

` It will be manifest, fro `the foregoing,

operations and functions. Infact.. some of the featuresof one form may readily be used in combination with the features of the other form, e. g., the modified construction does not embody my improved means for retaining the bolt against surreptitious movement by means of a screw-driver and thc like, as is embodied in my preferred form. It will, therefore, be manifest that this invention embodies many novel and meritorious features and thatI some of these features may be`utilized inthe manufacture of devices of the class described without, necessarily, employing all.
